Compact encoder offers high speed motion synchronisation for PLCs: Wachendorff covers PROFINET IRT in its WDGA absolute encoder range

As a recent addition to its PROFINET IRT protocol variants, Wachendorff’s WDGA 58F absolute magnetic encoder features a minimum bus cycle time of 125 µs which is eminently suited to tightly synchronised multi-axis motion control on the fastest PLCs. Available in the UK from Variohm EuroSensor, the 58 mm diameter encoder is also reckoned to be the world’s smallest PROFINET encoder with a nominal length of only 46.5 mm.

Wachendorff’s WDGA series absolute encoders, are characterised by their single- plus multi-turn functionality and the unique patented magnetic scanning principle that offers exceptionally high-precision position and velocity measurement with extreme durability and long life - without the use of wear-prone gears or batteries. Backed by a five-year warranty, the WDGA is available with a extensive choice of mounting and interfacing options, including CANopen, SSI, RS485, J1939 and PROFIBUS, to ensure flexibility across a very wide range of machine architectures.

The -58F PROFINET IRT version includes a 16 bit single-turn QuattroMag® technology resolution and EnDra® technology multi-turn capability to 43 bits. This translates to an angular accuracy and repeat accuracy of ± 0.0878° (=12 bit). Programmable parameters include steps or counts per revolution, presets, scale and count direction as well as MRP (Media Redundancy Protocol) specific values for PROFINET IRT to ensure safe operational use.

The WDGA-58F features a clamping flange mount with a choice of 6, 8 or 10 mm shaft diameters (plus a 3/8” option) and is one of five PROFINET IRT models offering mechanical mounting options including synchro flange, hollow bore and other clamping flange variants.
Across the WDGA range generally, the elevated axial and radial shaft load capacity contributes greatly to their high resilience. The durable encoder, available in 36 and 58 mm nominal diameters, has an aluminium housing with IP67 protection class as standard and shaft sealing to IP65 (IP67 optional). Temperature range is typically from -40 °C to +85 °C. Customised interfacing and specification variations are available on request.

Variohm EuroSensor supplies and fully supports Wachendorff’s complete range of absolute and incremental shaft encoders and measurement components. Further information is available at or by calling +44 (0) 1327 351004.
